采用电泳沉积法在Si(111)衬底上制备出了GaN薄膜。用X射线衍射(XRD)、傅立叶红外吸收(FTIR)谱、X射线光电子能谱(XPS)和扫描电镜(SEM)对样品的结构、组分和形貌进行了分析。结果显示所得样品为六方纤锌矿结构的GaN多晶薄膜。
GaN thin films were prepared on Si(111) suhstrates by eleetrophoretie deposition (EPD) technique. Measurement results by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) indicate that the polycrystalline GaN films with hexagonal wurtzite structure were successfully grown on the Si(111) substrates. The surface morphology of the as-prepared GaN films was examined by scanning electron microscopy (SEM).
